Title:
GAS INTRODUCING/RETAINING DEVICE, GAS INTRODUCING/RETAINING METHOD, AND GAS RELEASE HEAD
Document Type and Number:
WIPO Patent Application WO/2017/149654
Kind Code:
A1
Abstract:
[Problem] To provide: a gas introducing/retaining device and a gas introducing/retaining method that enable an increase in the amount of gas that can be dissolved in a liquid; and a gas release head used for a gas introducing/retaining device and a gas introducing/retaining method. [Solution] The present invention is provided with: a liquid storage tank 10 in which a liquid is stored; a gas release head 20 which has multiple pores having a pore diameter of at most 2.5 μm; a gas supplying means 30 that supplies a gas to the gas release head 20; and a vibration application means 40 which has a vibrator 41 for applying vibration to the gas release head 20, wherein the gas is released from the gas release head 20 by continuously applying vibration to the gas release head 20 immersed in the liquid. The vibration that is applied to the gas release head 20 by the vibrator 41 is set to have a frequency not lower than 30 kHz and an amplitude of not larger than 1 mm. The amount of the gas supplied to the gas release head 20 is adjusted so as to satisfy: (volume (μm3/min) of gas released from a single pore of gas release head 20)/(vibrational frequency (Hz) of vibrator 41)≤300.
